【正文】 s were characterized by the techniques of XRD、NH 3TPD、 H2TPR and BET, binding CH4合成氣在連續(xù)式步階反應器上直接合成 C2+含氧化合物的研究IVtheir activity data and a variety of characterization results to analyse the catalyst performances. The main conclusions were as follows：(1) On the CuCo bimetallic catalysts with various carriers, the order of C2+ oxygenates yield and selectivity is CuCo/TiO2 CuCo/Al2O3 CuCo/SiO2.(2) The suitable medium acidity and acid strength is beneficial to improving catalytic activity of the catalysts for the synthesis of C2+ oxygenate with CH4 and synthesis gas.(3) It is concluded that the interaction between the TiO2 and the active metal CoCu and the good dispersion of CoCu/TiO2 in the catalysts improve the catalytic activity.(4) The catalyst sample impregnated first with Cu has the highest activity and the yield of C2+ oxygenate is mgh1.(5) The impregnation sequence influences the acidity of the catalyst. The way impregnated first with Cu then Co is beneficial to the formation of medium acid and the medium acid is beneficial to the conversion of CH4 and syngas. Then that coimpregnated with Cu and Co is conducive to the formation of strong acid, but the strong acid restrains the conversion.(6) The impregnation sequence influences the existing state of Cu, The way impregnated first with Cu then Co is conducive to the formation of highly dispersed CuO fragmented crystallite particles or clusters.CH4合成氣在連續(xù)式步階反應器上直接合成 C2+含氧化合物的研究VKEY WORDS：CH 4, syngas, direct synthesis, C2+ oxygenates, CuCo catalystCH4合成氣在連續(xù)式步階反應器上直接合成 C2+含氧化合物的研究VI目 錄摘 要 ...........................................................................................................................................IABSTRACT................................................................................................................................I第一章 前 言 .........................................................................................................................1 選題背景及意義 ...............................................................................................................................1 文獻綜述 ...........................................................................................................................................3 甲烷活化的研究概述 ..................................................................................................................3 CH4 活化催化劑活性金屬的研究 ...........................................................................................6 CH4 活化催化劑載體的研究 ...................................................................................................9 一氧化碳的活化與轉化 ............................................................................................................10 CO 與催化劑表面的相互作用 ..............................................................................................10 H2 與 CO 的共吸附 ................................................................................................................11 甲烷，一氧化碳共活化轉化 ....................................................................................................12 CH4CO 直接合成乙酸的研究 ..............................................................................................12 CH4CO 直接合成乙醛的研究 ..............................................................................................14 本研究已有的工作基礎及本論文研究重點 ...............................................................................15第二章 實驗部分 .....................................................................................................................17 實驗所用化學試劑、原料與儀器設備 .......................................................................................17 化學試劑與原料一覽表 ..........................................................................................................18 實驗儀器 ..................................................................................................................................18 催化劑的設計和制備 ...................................................................................................................18 催化劑設計的指導思想 ..........................................................................................................18 催化劑的制備 ..........................................................................................................................19 催化劑的活性評價 .......................................................................................................................20 活性評價方法及裝置 ..............................................................................................................20 分析設備及分析條件 ..............................................................................................................21 催化劑表征 ..............................................................................................................................22CH4合成氣在連續(xù)式步階反應器上直接合成 C2+含氧化合物的研究VII第三章 載體的選取對催化性能的影響 .................................................................................23 催化劑的活性評價結果 ...............................................................................................................23 催化劑 NH3TPD 表征 .................................................................................................................24 催化劑 XRD 表征 .........................................................................................................................25 催化劑 H2TPR 表征 ....................................................................................................................26 結論 ...............................................................................................................................................27第四章 Cu/Co 浸漬順序對 CuCo/TiO2 催化劑性能的影響 ................................................28 催化劑的活性評價結果 ....................................
